Do not you yet understand, that whatever enters in at the mouth goes into the belly, and is cast out into the draught?…
If you can drive a man from outward vice, how far have you improved him if he lives in inward sin? You have benefited him as far as the sight of man is concerned, but not before God. There was a man killed on Holborn Hill this week, and I have heard that there was little or no external appearance of injury upon his body. He had been crushed between an omnibus and a cart, and all the wounds were internal, but he died just as surely as if he had been beaten black and blue, or cut into a thousand gashes. So a man may die of internal sin; it does not appear outwardly for certain reasons, but he will die of it just the same if it be within. Many a man has died from internal bleeding, and yet there has been no wound whatever to be seen by the eye. You, my dear hearer, may go to hell as well dressed in the garnishings of morality as in the rags of immorality.
(C. H. Spurgeon.)
